Subject: soc: qcom: smsm: fix child-node lookup

From: Johan Hovold <[email protected]>

[ Upstream commit 8804517e9fc16c10081ff5e42e7d80704973a8e2 ]

Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children.

Note that the original premature free of the parent node has already been fixed separately.

Also note that this pattern of looking up the first child node with a given property is rare enough that a generic helper is probably not warranted.
